AUTOMOBILE RADIATOR.

Application liled May l,

T0 all w/zoni t may concern:

Be it known that I, EDWARD HAGEN, a citizen of the United States, residingl at lelican Rapids, in the county of Otter 'lail an-d Stat-e of Minnesota, have invented a new and useful Automobile Radiator, of which the following is a specification.

This invention relates to radiators, particularly the type commonly used on motor vehicles, and its object is to provide'means for equalizing the circulation of water therethrough, so as to cool the same most effectively in summer, and keep all parts of the radiator warm'in winter to prevent it from freezing.

The detailed construction of the invention and the principles of its operation will be fully explained in the following detailed description, which is to be read inconnec-` tion with the accompanying drawing illustrating the preferred embodiment thereof.

In the drawing:

Figure 1 is a front elevation of a radiator with the invention embodied therein, parts thereof being broken away and shown in section.

.Figure 2 is a vertical section taken on the line 2-2 of Figure 1.

The radiator to which the invention is applied comprises a lower manifold or pan 5 connected by a series of small tubes 6 to an upper manifold 7. The upper manifold 7 has an inlet opening 10, through which the water circulates from a hose 11 leading from the water jacket of the engine. The lower manifold 5 has an outlet opening 8 from which the lwater returns through a hose 9 to the water jacket. The radiator has angle irons 12 secured thereto by means of which it is attached to the automobile chassis, and the front side of the radiator is covered by a4 screen 13. 'Ihe u pper manifold 7 is provided with a filler neck 14, which is closed by a cap 15, and the lower manifold 5 is provided with the usual drain cock 16.

In radiators as heretofore constructed, the greater part of the circulation takes place through the tubes located immediately above the outlet opening 8, and in the summer the radiation is insufficient to properly cool the y engine, while in extremely cold weather, owing to the very limited circulation through the tubes most remote from the outlet 8, the water therein is liable to become 1925.` Serial No. 27,197.

frozen. In order 'to avoid such results, V

manifold through the opening Sto be drawnpartly" from each side of the partition, thereby Y causing a substantially equal volume of fiofwA i through the tubes at either side of the ral i y -diator. The major portion of this partition plate 17 is substantially horizontal extending across the manifold 5. One end of. the partition plate is curved downwardly, as at 18, and attached to the lower wall of the manifold 5 beneath the outlet 8, so that sub.v stantially one-third of the opening is beneath the partition plate. i plat-e is curved upwardly, as at 19, and at-l tached to the upper wall of the manifold 5 at a distance substantially two-thirds ofthe width of the radiator from the'side nearest the outlet opening. substantially one-third of the water discharged through the opening 8 is drawn from the remote side of the radiator, after flowing downwardly through one-third of the tubes, which are located farthest from the outlet opening 8. Thus, a substantially equal flow is insured through the tubes at either side of the radiator, and their tempertture and radiation therefrom is equalizec.

In the typeof radiator shown herein, the continuous circulation of the water is generally insured by means of a. rotary pump. The invention, however, is not limited in its applicati-on to this particular type of radiator, but may be used to advantage in any type of radiator, whether the circulation iseifected by a pump or by gravity. Modifications may also be made in the size, shapev and arrangement of the plate 17 without any material departure from the essential principles of the invention. It is my intention, therefore, to include all such variations e and modications within the scope of what is claimed.

What is claimed is: Y

1. In an automobile radiator, the combination of a manifold having an outlet opening, a manifold-having an inlet opening, a series of passageways connecting the two manifolds, and a partition plate extending across the outlet manifold in front of the outlet opening, so that a portion of the dis- The other end of the By this construction charge is drawn from eaoh side of the partition plate, said partition plate being eX- tended laterally so that one portion of the stream will be drawn from the remote side of the radiator.

2. In an automobile radiator, the combination of a lower manifold having an outlet opening, an upper manifold having an inlet opening, a series of passageways connecting the two manifolds, and a partition in the lower manifold, the major portion of the partition being horizontal and joiningl the front and rear walls of the manifold, one end of the partition lbeing curved upwardly to meet the upper wall of the manifold and the other end Crossing the outlet ope-ning and terminating in a downwardly curved portion which meet the lower Vall of the manifold.

3. In an automobile radiator, the combination of a manifold having an outlet opening near one end thereof, a manifold having an inlet opening, a series of passageways connecting the two manifolds, and a partition joining the front and rear walls of the outlet manifold and extending across the outlet opening and causing the outlet stream to be drawn from opposite sides thereof, one end of the plate being Curved to meet the wall of the manifold which is opposite to said passageways, the other end of the plate being extended toward the end of the manifold remote from the outlet and curved to meet the wall through which the passageways lead and dividing the same into the two sections Iwhich are substantially proportional to the respective portions of the outlet strean'i.

4. In an automobile radiator, the combination of a lower manifold having an outlet opening near one end thereof, an upper manifold having an inlet opening, a series of passageways Connecting the two inanifolds, and a partition plate joining the front and rear walls of the lower manifold and extending across the outlet opening and dividing the outlet stream so that approximately one-third of the same comes from beneath the partition, said plate, as it crosses the outlet opening, being curved downwardly to meet the lower wall of the manifold, the other end of the plate being extended toward the end of the manifold remote `from the outlet and Curved upwardly to meet the upper wall of the manifold at. a point distant two-thirds of the length of the manifold from the outlet end, whereby to effect an equalization of the fio-w through the tubes at either eide of the radiator.

In testimony, that I Claim the forego-ing as my own, I have hereto alliXed my signature.
